Does anybody have a scag 36" mower with a 15hp Kaw? Or if not maybe just a scag? It seems like it has lost its quality of its cut, and yes i just put sharp blades on. It seems like the front casters are pushing the grass down and theres not enough suction to pull it up in time. do you recommend putting different blades on, b/c i have the stock ones on. or do you recommend changing the spaces under the deck by the blades b/c i heard on some thread that it increases the suction under the blade, like if the blades higher in the deck does that improve the suction?
